hi there guys i've got a stage 1 megane 230 with a standard forge blow off valve just wondered if i needed the upgraded spring or not
Actually yeah, I am stage 1, so be nice to know best spring for the DV. Someone hopefully has the answer and its not just down to personal preference.
Depends on what boost you're making. Over 1 bar / 15psi you should use a yellow spring. http://www.forgemotorsport.co.uk/content.asp?inc=product&cat=160201&product=FMDVTUN
Green spring will be fine. You could upgrade to a yellow one if you feel the need. i use blue springs in my car at 1.3bar of boost.
